Abstract

Presse comportant un mécanisme de réglage de la hauteur de fermeture du coulisseau et de protection contre les surcharges. Ce mécanisme comporte un cylindre monté sur l'une des pièces constituées par le coulisseau et la bielle reliés au vilebrequin du mécanisme de commande, et un piston monté sur l'autre de ces pièces et pouvant exécuter un mouvement alternatif dans le cylindre Des organes limitent le mouvement du piston dans un sens et un circuit hydraulique refoule un fluide sous pression entre le piston et le cylindre. Ce fluide peut être évacué lorsque le coulisseau est soumis à une surcharge, afin que le piston puisse se déplacer par rapport au cylindre en sens opposé au precédent. Domaine d'application : presses mécaniques.
